Unzipped files with a directory disappear after saving from the editor

Whenever I attempt to unzip a file filled with any content to a Lesson activity's content page the folder gets deleted as soon as I save the page. The zip file remains but the folder is no longer there. I discovered that if I upload each file individually, Moodle saves the files with no problem. Adding the folders is a little bit harder since it seems the "add folder" option is missing. Should I assume that a content page in a lesson functions similarly to an html page activity?

See attachment for details on how to reproduce error.

Adrian - The problem here is that the file manager in Atto or tinyMCE can not cope with a directory being created via an unzipped file. When the page is saved the unzipped directory is deleted and any reference to the files in that directory are also lost.
